I'm pretty new to ubuntu, and running 8.10 as a virtual machine on my macbook pro with leopard via parallels desktop 4. I'm trying to turn on my visual effects, but whenever i do it attempts to scan for the necessary drivers, and appears not to find them. It then simply tells me that "desktop effects could not be enabled." I'm wondering what these drivers are that I'm missing, and how I would go about obtaining and installing them.
Thank you all in advance,
Eric
